He takes a shower

Mark continued to let his mind drift over today's events and though about what to do with his powers. He couldn't help but imagine his sister naked again though. He closed his eyes and remembered how hot she looked. For a moment he was tempted to stop time again and quickly head downstairs for another look, maybe more this time.

He decided against it though. Mark wanted to try and limit the use of his powers till he was sure he could use them without anymore incidents. Instead he settled for just slowly jerking his still semi hard cock while thinking about Ashley. But As he stood there he couldn't help but feel slightly embarrassed. He couldn't help but feel as if someone was in the room with him, watching.

Markdecided to give his powers another test. He focuses on stopping time just as he had earlier. After a few seconds the bathroom fell silent and the water was frozen in mid air all around him. It was an amazing site. He took a few moments to play with the frozen water pushing it around said it was in zero gravity. He tried pausing time and restarting it again some more for practice.

After a while Mark decided he'd better finish up. He switched off the water and stepped out the shower. He dried himself off with a towel and went to wrap it around his waste when he realised he was still hard. He decided to just leave it, he was only going to his room and should fix itself he thought.

After wrapping the towel around his waist mark unlocked the door and stepped out into the hall. As he did so he walked straight into his sister. He felt her chest press against his as they briefly collided. The neither of them was moving that quickly but the impact was enough to send them both stumbling back slightly. As mark tried to steady himself he accidentally let go of his towel and it fluttered down leaving him exposed in front of his sister.

"Hey! Each where you're…" Ashley started before realising her brother was standing naked in front of her "oh my god!" She giggled.

Mark was stunned as he realised his state. His first instinct was to stop time. He frantically tried to but it was as if something was interfering with his abilities.

From his sisters point of view Mark was now just standing naked and stunned in the wall way. She took this time to reach down and snatch Mark's towel off the floor and tossed it downstairs, out of reach.

"Hey!" Mark yelled as he seemingly recovered from his embarrassment.

His sister took a step back and eyed him up. "Not bad bro, not bad. You obviously enjoyed your shower" she giggled as she motioned to his waist "you're as straight as a ruler"

Mark tried to past her and get back to his room but she moved to block him.

"Going some where?" She asked playfully "you're not embarrassed are you? what's the matter it's nothing I haven't seen before?"

"Yeah, when we were little kids" mark said as he tried to squeeze past her but ash was still blocking him. He tried to push past her but he just ended up pressed between her and the wall with his rock hard cock pressed directly against her.

"Yeah I guess you're a man now" she said in a surprisingly seductive tone.

Mark eventually squeezed past her and slipped back into his own room.
